摘　　要：温度的分布不均会导致部件内部产生热应力,在结构分析中常会遇到需要考虑温度场对应力分布影响的情况。由于深海高压环境模拟实验舱模拟深海低温高压环境,在工作过程中其强度不仅与舱体内部水压力作用有关,还会受到舱体内部温度的影响。运用ANSYS/Workbench有限元分析软件,对压力舱筒体进行热-应力耦合分析,克服了在温度和压力共同作用时理论强度计算的困难,分析结果显示该舱体满足分析设计标准JB 4732—95的要求,通过与按第四强度理论未考虑温度影响时的计算结果对比,发现温度对舱体的影响不大,这为后续实验舱的结构优化等提供理论依据。Uneven temperature distribution can lead to thermal stress in the components,in the process of structural analysis,the influence of the temperature field on the stress distribution should be considered in many cases.Due to the high pressure tank simulates the deep-sea high pressure and low temperature environment,during the working process,its strength is affected by the water pressure as well as the temperature.Using the ANSYS / Workbench finite element software,analyzed the heat-stress of the pressure tank,overcame the theoretical calculations difficulties of the interaction of temperature and pressure,the analysis showed that the tank can meet the requirements of the standards of JB 4732—95,then contrasted with the fourth strength theory＇s results without considering temperature impact,found that the temperature has little effect on the tank,these provide theoretical basis for subsequent structural optimization.
